5-HP Oversized Motor & Drive 5-HP Oversized Motor & Field Supplied High Static Drive
(ii)
(ii)
5-HP Oversize Motor with Field Supplied Motor Sheave 1VP50 required. Field Supplied Belt may be necessary.
*For 380V/60 Hz units, the oversized motor is used as the standard motor. Refer to "Motor & Sheave/Fan Speed" tables to determine operating range.
For Standard Evaporator Fan Speed (RPM), reference Table 50.
For Standard Motor & High Static Drive Accessory Fan Speed (RPM), reference Table 52.
For Oversized Evaporator Fan Speed (RPM), reference Table 53.
Fan motor heat (MBH) = 3.15 x Fan BHP.
Notes:
Data includes pressure drop due to standard filters and wet coils. No accessories or options are included in pressure drop data.
Refer to Table 54 to determine additional static pressure drop due to other options/accessories.
Factory supplied motors, in commercial equipment, are definite purpose motors, specifically designed and tested to operate reliably and continuously at all
cataloged conditions. Using the full horsepower range of our fan motors as shown in our tabular data will not result in nuisance tripping or premature motor
failure. Our product's warranty will not be affected.
